Arripis Truttacea
''Arripis truttacea'', the Western Australian salmon, is a species of marine ray-finned fish within the genus ''Arripis'', the only genus within the family Arripidae. It is endemic to the seas off southern Australia. Description ''Arripis truttacea'' has a streamlined, moderately deep, slightly elongate body which is a little compressed with a relatively narrow caudal peduncle and a moderately small head. The eyes are quite small with an obvious growth of transparent adipose tissue on the anterior and posterior edges of the eye on larger fish. There is a series of fine serrations along the lower edge of the preorbital bone but these largely disappear in larger fish. The mouth is moderate in size and is oblique, its maxillae reaches a level below the centre of eyes. There is a narrow band of small pointed teeth in each jaw. The body, except for the lower jaw, snout and area above the eyes is covered with moderately small, very finely ctenoid and larger specimens feel smooth to the ...

Georges Cuvier
Jean Léopold Nicolas Frédéric, Baron Cuvier (; 23 August 1769 – 13 May 1832), known as Georges Cuvier, was a French natural history, naturalist and zoology, zoologist, sometimes referred to as the "founding father of paleontology". Cuvier was a major figure in natural sciences research in the early 19th century and was instrumental in establishing the fields of comparative anatomy and paleontology through his work in comparing living animals with fossils. Cuvier's work is considered the foundation of vertebrate paleontology, and he expanded Linnaean taxonomy by grouping classes into phylum, phyla and incorporating both fossils and living species into the classification. Cuvier is also known for establishing extinction as a fact—at the time, extinction was considered by many of Cuvier's contemporaries to be merely controversial speculation. In his ''Essay on the Theory of the Earth'' (1813) Cuvier proposed that now-extinct species had been wiped out by periodic catastrophi ...

Esperance, Western Australia
Esperance is a town in the Goldfields–Esperance region of Western Australia, on the Southern Ocean coastline approximately east-southeast of the state capital, Perth. The urban population of Esperance was 12,145 at June 2018. Its major industries are tourism, agriculture, and fishing. History European history of the region dates back to 1627 when the Dutch vessel ''Gulden Zeepaert'', skippered by François Thijssen, passed through waters off the Esperance coast and continued across the Great Australian Bight. French explorers are credited with making the first landfall near the present day town, naming it and other local landmarks while sheltering from a storm in this area in 1792. The town itself was named after a French ship, the ''Espérance'', commanded by Jean-Michel Huon de Kermadec. fr , Espérance , label=none is French for "hope".

Hopetoun, Western Australia
Hopetoun is a town on the south coast of Western Australia in the Shire of Ravensthorpe. Located on Mary Ann Harbour, Hopetoun is south-east from capital city Perth and west of Esperance. History Mary Ann Harbour was named in November 1865 by the sealer James Sale on the cutter ''Mary Ann''. The ''Mary Ann'' was owned by whaling master John Thomas of Cheyne's Beach, east of Albany, who had named it after his eldest daughter. Hopetoun was established in 1900 as the port servicing the Phillips River goldfield, named after the first Governor-General of Australia, John Hope, 7th Earl of Hopetoun. The townsite was gazetted on 9 February 1901. The town became a shipping port for the mining industry, with a jetty built in 1901, the terminus of a railway line between Hopetoun and Ravensthorpe that operated from 1909 to 1935. The port was closed in 1937, with the jetty remaining until its destruction in 1983. Some of the town's electricity is generated by a wind-diesel system. ...

Leeuwin Current
The Leeuwin Current is a warm ocean current which flows southwards near the western coast of Australia. It rounds Cape Leeuwin to enter the waters south of Australia where its influence extends as far as Tasmania. Discovery The existence of the current was first suggested by William Saville-Kent in 1897. Saville-Kent noted the presence of warm tropical water offshore in the Houtman Abrolhos, making the water there in winter much warmer than inshore at the adjacent coast. The existence of the current was confirmed over the years, but not characterised and named until Cresswell and Golding did so in the 1980s. Track The West Australian Current and Southern Australian Countercurrent, which are produced by the West Wind Drift on the southern Indian Ocean and at Tasmania, respectively, flow in the opposite direction, producing one of the most interesting oceanic current systems in the world. The ‘core’ of the Leeuwin Current can generally be detected as a peak in the surface te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Busselton
Busselton is a city in the South West region of the state of Western Australia approximately south-west of Perth. Busselton has a long history as a popular holiday destination for Western Australians; however, the closure of the Busselton Port in 1972 and the contemporaneous establishment of the nearby Margaret River wine region have seen tourism become the dominant source of investment and development, supplemented by services and retail. The city is best known for the Busselton Jetty, the longest wooden jetty in the Southern Hemisphere. History Pre European settlement and 19th century Before white settlement in 1832, and for at least 40,000 years, the Busselton area was home to the Noongar Aboriginal people from the Wardandi and Bibulman language/ancestral groups. The colonisation of Western Australia in 1829 had a major impact on the life of the Noongar people. Many towns in the Busselton area, such as Wonnerup, Yallingup and Carbunup River, still hold their origina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Leeuwin
Cape Leeuwin is the most south-westerly (but not most southerly) mainland point of the Australian continent, in the state of Western Australia. Description A few small islands and rocks, the St Alouarn Islands, extend further in Flinders Bay to the east of the cape. The nearest settlement, north of the cape, is Augusta. South-east of Cape Leeuwin, the coast of Western Australia extends much further south. Cape Leeuwin is not the southernmost point of Western Australia, with that distinction belonging to West Cape Howe, which is to the southeast, near Albany. In Australia, the cape is considered where the Indian Ocean meets the Southern Ocean, but most other nations and bodies consider that the Southern Ocean exists only south of 60°S. Located on headland of the cape is the Cape Leeuwin Lighthouse and the buildings that were used by the lighthouse-keepers. Cape Leeuwin is considered one of the three "great capes" of the world. Use of name Cape Leeuwin is often group ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spawn (biology)
Spawn is the Egg cell, eggs and Spermatozoa, sperm released or deposited into water by aquatic animals. As a verb, ''to spawn'' refers to the process of releasing the eggs and sperm, and the act of both sexes is called spawning. Most aquatic animals, except for aquatic mammals and marine reptile, reptiles, reproduce through the process of spawning. Spawn consists of the reproductive cells (gametes) of many aquatic animals, some of which will become fertilized and produce offspring. The process of spawning typically involves females releasing Ovum, ova (unfertilized eggs) into the water, often in large quantities, while males simultaneously or sequentially release spermatozoa (milt) to fertilize the eggs. Most fish reproduce by spawning, as do most other aquatic animals, including crustaceans such as crabs and shrimps, molluscs such as oysters and squid, echinoderms such as sea urchins and sea cucumbers, amphibians such as frogs and newts, aquatic insects such as mayflies and mos ...

Baitfish
300px, Feeder Goldfish are common baitfish. Bait fish (or baitfish) are small-sized fish caught and used by anglers as bait to attract larger predatory fish, particularly game fish. Baitfish species are typically those that are common and breed rapidly, making them easy to catch and in abundant supply. Overview Examples of marine bait fish are anchovies, gudgeon, halfbeaks such as ballyhoo, and scad. Some larger fish such as menhaden, flying fish or ladyfish may be considered bait fish in some circles, depending on the size of the gamefish being pursued. Freshwater bait fish include minnows from the carp family ( Cyprinidae), sucker family (Catostomidae), topminnows from the killifish suborder (Cyprinodontoidei), shad family (Clupeidae), sculpin of the order Scorpaeniformes and sunfish family (Centrarchidae), excluding black basses and crappies. Bait fish can be contrasted with forage fish. ''Bait fish'' is a term used particularly by recreational fishermen, although ...

Avicennia
''Avicennia'' is a genus of flowering plants currently placed in the bear's breeches family, Acanthaceae. It contains mangrove trees, which occur in the intertidal zones of estuarine areas and are characterized by its "pencil roots", which are aerial roots. They are also commonly known as ''api api'', which in the Malay language means "fires", a reference to the fact that fireflies often congregate on these trees. Species of ''Avicennia'' occur worldwide south of the Tropic of Cancer. The taxonomic placement of ''Avicennia'' is contentious. In some classifications, it has been placed in the family Verbenaceae, but more recently has been placed by some botanists in the monogeneric family Avicenniaceae. Recent phylogenetic studies have suggested that ''Avicennia'' is derived from within Acanthaceae, and the genus is included in that family in the Angiosperm Phylogeny Group system. Designation of species is made difficult by the great variations in form of ''Avicennia marina''. B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Posidonia
''Posidonia'' is a genus of flowering plants. It contains nine species of marine plants ("seagrass"), found in the seas of the Mediterranean and around the south coast of Australia. The APG system (1998) and APG II system (2003) accept this genus as constituting the sole genus in the family Posidoniaceae, which it places in the order Alismatales, in the clade monocots. The AP-Website concludes that the three families Cymodoceaceae, Posidoniaceae and Ruppiaceae form a monophyletic group. Earlier systems classified this genus in the family Potamogetonaceae or in the family Posidoniaceae but belonging to order Zosterales. ''Posidonia oceanica'' has nitrogen fixation capabilities via symbiosis and other species may as well. Species This is a list of species that are contained by the genus: *''Posidonia angustifolia'' Cambridge and Kuo *''Posidonia australis'' Hook.f. South coast of Australia. *''Posidonia coriacea'' Cambridge and Kuo *''Posidonia denhartogii'' Kuo and Cambridge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
